in Electrical Characteristics
(1) When the voltage of VBAT pin is less than the threshold of UVLO, the output of CS pin forces low level.
(2) The Power path switch changes the path after the voltage of VO_BT is higher than V
(CS_DET)
. Before that, the power path of VOUT
comes from VO_BT pin; not VBK pin.
